Yes, though I might still read that and choose a pipe for ldapsearch.
How about adding this sentence:

[...] these features.  A Lisp program should prefer a pty when
interacting with a subprocess that prompts the user for information
(e.g., a password) because that feature of the subprocess was probably
developed and tested assuming a pty.  However, for subprocesses used by
Lisp programs [...]

AIUI, this is your main rationale for using a pty for ldapsearch --
though feel free to reword it.

Thanks,
